Figure 1: Annotations to help tell the story. **Please note, though:** some data reconciliation is needed. The data for the main line comes from Foodnet at https://wwwn.cdc.gov/foodnetfast/ but the data about the reduction target (11.4) and the baseline (15.0) come from https://www.healthypeople.gov/2020/topics-objectives/topic/food-safety/objectives, and they are based on slightly different numbers: https://www.healthypeople.gov/2020/data-search/Search-the-Data?nid=4478. I don't know where the 30% figure cited in the text comes from. Decreasing from 15 to 11.4 is a 26% reduction.

Figure 2: Basically the original with trend lines added and made prominent. The data jump around so much that it's hard to see what the trends are without them.

Solid lines represent the linear trends for each product.

Note: FSIS started sampling and testing chicken parts for *Salmonella* in 2015 as performance standards for this product category were implemented. The agency did not test any ground chicken products in 2014; therefore, no data is available.

Figure 3: One way to get both lines on the same axis is to express them as percentage change indexed to common point. Each line here is indexed against its 2006–08 average value.

Figure 4: Separates contamination and incidence into two charts so the can be on different axes. (4a and 4b) Contamination uses trend lines to clarify the trends.

The remaining charts for the other serotypes could be handled in the same way.
